OVERVIEW:
A large part (724 acres) of the downs including Mill Hill were presented to the people of Shoreham in 1937. Just over 30 acres still remain as public open land and a Local Nature Reserve. This is divided into about 11 acres of grassland and meadows above the ridge, about 9 acres of scrub, the copse and glades at the northern end, and about half of the prime Chalkhill Blue area of 6.4 acres of herbland remaining. 6 acres has been lost to a Sycamore woodland on the southern slopes. This is low fertility chalkland not suitable for grazing. The top area is effectively a wild meadow and the lower slopes a rabbit warren dominated by prostrate (not the upright form) Horseshoe Vetch, Hippocrepis comosa. |

Chalkhill Blues:
Mill
Hill is nationally important because of its population of Chalkhill
Blue Butterflies. Estimates of the numbers
are notoriously inaccurate. In the 1950s the population was estimated by
R. M. Craske to be 50,000. This may be an
exceptionally good year. I would estimate the numbers at that time to be
nearer 25,000 for Mill Hill only. After the cattle grazing and thorn incursions
the numbers plummeted to the most reliable estimate in 1960 of 6,000. The
new road and Sycamore woodland further denuded the Horseshoe
Vetch, Hippocrepis comosa,
and bare chalk downland to a figure I have estimated at a top figure of
3,000 Chalkhill Blue Butterflies at the turn of the millennium (counted
in 2003). Almost all these butterflies are now to be found on the six acres
of the lower slopes.

Two
Musk
Thistles were still flowering
by the Reservoir on Mill Hill, but after the deluge or for some other reason
the prickly stems were bent and the purple flowers were drooping down.
Just a few Sow Thistles
were noted on the road edge.

This mushroom was discovered on the edge of the meadow to the north of the upper car park on Mill Hill, believed to be the White Dapperling, Leucoagaricus leucothites. I do not think that the common name is actually used for this frequently encountered species?

It came as a great surprise to me to see a large yellow Brimstone Butterfly fly over the top meadow (north of the upper car park) on Mill Hill. It flew strongly in the direction of New Erringham. This was the first Brimstone Butterfly recorded in the month of November on these Nature Notes pages. Five minutes later a Speckled Wood Butterfly fluttered amongst the long grass south of the Reservoir on Mill Hill. On the plateau to the south of the upper car park, there were cow pats from the spring, despite the wetAugust.

There
were no butterflies seen in twenty minutes
before the forecasted cold weather. There
were very few nectar plants on Mill Hill, one flower
of Devil's Bit Scabious,
one Autumn
Gentian, one Stemless
Thistle, a few bedraggled Hawkbits
and some Wild Basil on
the lower slopes. A dimunitive Ragwort
was seen on the upper plateau and Musk Thistle
and Sow Thistle
on the upper part near the Reservoir.

Two
Kestrels
were performing sparring acrobatics over the Copse
and scrub on Mill Hill. They were both about the same size, so I assume
that these were male birds fighting over territory. There
is usually just one male on Mill Hill seen hovering throughout the year.
A
single Musk Thistle
was still in flower by the Reservoir.
Singles of Spear Thistle
and Creeping Thistle
in flower were noted.
8 October
2008
After
five days of rain and poor weather the herb
layer of the lower slopes of Mill Hill
was still springy and firm under foot. A Peacock
Butterfly flew up and visited me. Otherwise
all the butterflies were at the northern
end and there were not very many of them, a handful of Meadow
Browns, a tatty male Adonis
Blue, at least one good condition male
Common
Blue and a Small
Copper.
On
the top near the Reservoir, a Buff-tailed
Bumbleebee
visited a Musk Thistle
still in flower. Spear Thistles
were also still in flower and I a noted a solitary Creeping
Thistle with a full flowering head.

There
was the faint bite of an autumn chill in the air on a morning of weak sunshine,
and the butterflies did not emerge until
near midday. At the northern end of the lower
slopes of Mill Hill, three species could be seen resting on Devil's
Bit Scabious and only later when the
sun came out did many of the butterflies emerge in numbers and fluttered
about so much that I could not be sure of their numbers.

Ten

Hill including Adonis Blues,
pristine Common Blues
and new Brown Argus
Butterflies emerged. The female Adonis
Blue has bars in the white outer rim of the
wing which is absent in the Common Blue
female (see the photographs above).
The numerous Autumn Gentian
on the upper plateau had ceased flowering. There were still plenty (20+)
of dried out cow pats
from the cattle grazing
in the spring.

12
September 2008
On
the lower slopes of Mill Hill, the first
butterfly seen was Common Blue,
followed later by a female of the species, a few male Adonis
Blues
scattered over the slopes with a congregation of both sexes on the Devil's
Bit Scabious at the northern end, totalling
seven males and seven females, plus six Meadow
Browns (gender undetermined, mostly males),
two Small Heath Butterflies,
at least one Treble-bar Moth
and a faded Pyrausta nigrata
moth. Three Meadow Browns
and a Common Blue
were spotted in the Old Erringham pasture in the vicinity of the stile.
Amongst the scrub, a Speckled Wood
fluttered by and two Small Heaths
were seen courting. In the top meadow there were three Common
Blue males and four more Meadow
Browns plus a surprise Wall
Brown.
9 September
2008
It
was still much too overcast, with spots of rain, for butterflies
to be out and about if they had survived the atrocious weather.
A quick check on the Privet-inundated
lower
slopes of Mill Hill produced seven male Adonis
Blues, ten Meadow
Browns and a Small
Heath Butterfly. There were no Chalkhill
Blues seen. The scrub added a Speckled
Wood, and the upper area of Mill Hill
another Meadow Brown
and another Small Heath.
Devil's
Bit Scabious was seen in flower for the
first time this year. Despite four days of rain and the whole of the summer,
there were still dried-out cow pats
on the Autumn Gentian
covered plateau south of the upper car park. Most of the Autumn
Gentian was not in flower.

August 2008
After
four days of poor weather, the butterflies
were out again. They were common on the lower
slopes of Mill Hill with 25+ Chalkhill
Blues
including
a few females,
62 male Adonis Blues,
an estimated 75+
Meadow
Browns
of
both sexes, frequent
Common Blues
(estimated
12+) including very small ones, one confirmed
Gatekeeper,
a few Large Whites,
at least one Green-veined White,
two Speckled Woods on
the southern steps, and a Wall Brown.
I returned by the ridge route where I saw two more Speckled
Woods, a pristine female Adonis
Blue on Marjoram,
and a further two Chalkhill Blues
fluttering around the very short grass on the rim of the ridge. The only
other butterfly species seen on the hill were Holly
Blues with at least two fluttering around
the large hedge on the side of the road south of Mill
Hill Nature Reserve.

August 2008
With
the weather conditions ameliorated enough to make a trip to Mill
Hill worthwhile, it seemed as though I have missed the main emergence
of Chalkhill Blue
Butterflies for 2008
as the very poor showing of 43 (with one female) on the 1.2 acre transect
on the lower slopes indicated. There were
a further three male Chalkhill Blues
seen on the upper part of Mill Hill and another six on the Mill
Hill Cutting. There were nearly as many fresh male Adonis
Blues with 37 noted on the lower slopes,
not to be confused with Common Blues
with
29+ recorded on Mill Hill, including six on the lower slopes, as well as
three on the Pixie Path and at least one
on the Coastal Link Cyclepath south of
Old Shoreham. A small butterfly flitting
about a long grass meadow on the top of Mill Hill turned out to be a pristine
Brown
Argus
Butterfly when it settled. A total of
nine of this species were recognised on Mill Hill with six of these occurring
over the lower slopes. Mill Hill hosted
frequent
Gatekeepers
and
Meadow
Browns.
Wall
Browns appeared in the front of me on
four occasions, three on Mill Hill and one on the Pixie Path. A Marbled
White was a welcome surprise over the
lower slopes of Mill Hill.

July 2008
The
Chalkhill
Blues were slow to appear this year, as
the count of a mere 81 (including two females) plus two male Adonis
Blues on the lower
slopes of Mill Hill, indicated. There were a handful of Common
Blues
of both sexes noted on both the lower slopes and upper meadows. I was not
in mood for counting butterflies, but the other butterflies seen on Mill
Hill in the middle of a sunny day were Large
Whites and Speckled
Woods, plus the occasional Marbled
Whites (5), Small
Skippers (3+), Wall
Browns (a courting pair), Peacock
Butterflies (2) and Holly
Blues (2). The usual Gatekeepers
and
Meadow

were
present everywhere. Six-Spot Burnet Moths
were frequently seen mostly on the upper meadows of Mill Hill. The small
pyralid
moth
Synaphe
punctalis was identified from
the lower slopes.

Burnet Moths
Hundreds of the small herb Autumn Gentian were poking through the chalky area on the upper plateau of Mill Hill, immediately north of the Reservoir. A handful were in flower for the first time this year. A few Round-headed Rampion were in flower amongst them and only a handful of these blue flowers were seen on a passage trip scattered over the upper hill. |

Even
more spectacularly, the number of butterfly
species seen on 27
July 2008 has to be increased by one to 22
species, as a second brood male Adonis
Blue was identified on the lower
slopes of Mill Hill and one was seen there yesterday as well. My visit
was to look for the main emergence of Chalkhill
Blues and make a count on the 1.2 acre
transect of the lower slopes, which came to 68 males. There were also 15+
Chalkhill
Blues on the Mill
Hill Cutting (south-west corner), two seen by the stile to the Old
Erringham pasture, and another six as I returned by the quickest ridge
route through the tunnel of Hawthorn. There were frequent
Gatekeepers
and
Meadow
Browns
everywhere,
with an occasional prevalency
of Speckled Woods
in the shade, plus a Peacock
and at least one Small Heath
on the lower slopes of Mill Hill. A Marbled
White flew amongst the long grass south
of the Reservoir on Mill Hill. On the ridge path a single Marjoram
plant attracted five Gatekeepers
and a Peacock Butterfly.

Over
200 butterflies of 15 species were seen in
about two hours on Mill Hill and the approaches
with 37 Chalkhill Blues
(including two females)
seen mostly on the lower slopes. Another
notable was the first two of the second brood Brown
Argus

White on Mill Hill was confirmed with
a close-up look. Six Peacock Butterflies
were seen.
On
Mill Hill only, Chalkhill

A
late afternoon visit to Mill Hill was undertaken for the purpose of ascertaining
the extent of the covering of Horseshoe
Vetch,
Hippocrepis
comosa, which could be seen from Old
Shoreham by the Toll Bridge. It was
at least as spectacular as the best year, but a close inspection revealed
that a proportion (c 5%) of the flowers were already fading on the lower
slopes. The Horseshoe Vetch
was rather sparse on the middle and upper slopes. It is usually later in
these areas, but it still appeared much less than expected. At least
one Bird's Foot Trefoil
was seen. Other flowers noted were the poisonous White
Bryony,
Bryonia
dioica, mostly were the conservation workers had been on Mill Hill,
and the first sign of flowering Hound's
Tongue, Cynoglossum
officinale, notably near the Rabbit
burrows. The invasive Ground Elder, Aegopodium
podagraria, was noted on the upper
part of the hill.
Although,
it was too windy, too cool and too late in the day for butterflies,
a couple of enthusiasts said they had given up counting the Adonis
Blues
at over a hundred over a three acre area of the lower
slopes, and they also had two confirmed Green Hairstreaks on
the middle slopes above the ridge. This hairstreak
is only rarely recorded on Mill Hill. Their species count for Mill Hill
was 14 plus the first Cinnabar

My
first Wall Brown Butterfly
of 2008 and my
first Red Damselfly
were both seen near and in the copse of
Mill Hill. The first Brimstone Butterfly
was a bright yellow male seen over a clearing in the scrub, and then a
bright yellow male and white female appeared to be courting under the canopy
of the copse at the top of Mill Hill, until another yellow male came and
competitively interrupted the proceedings. Whereupon the female disappeared
and the males carried on jousting. Three Holly
Blue Butterflies fluttered around the
low lying scrub on the middle slopes of Mill Hill. The sun was not warm
enough for smallish blue butterflies to open their wings. Two Speckled
Woods danced under the copse at Mill Hill.
11 Grizzled Skippers,
about 12 Dingy
Skippers (one on the middle slopes) and
at least five Pyrausta nigrata pyralid
moths
were seen on the lower slopes.

I also
spotted my first Swallow
of the year on a low level flight so its pale orange belly underside could
be clearly seen.
Horseshoe
Vetch,
Hippocrepis
comosa, was much more prominent on
the lower slopes of Mill Hill and could be seen covering the lower slopes
before I descended the steps at the southern end. Dog
Violets were very common and Milkwort
was
all over the slopes.
A
male Pheasant
was surprised on a path before it trotted off into the Hawthorn scrub of
the north-west.

The
first
Dingy Skipper
of 2008 was seen
on the lower slopes of Mill Hill around
midday.
One Grizzled Skipper
was also spotted on a passage journey with a return route via the ridge.
Three
Small Tortoiseshells and
a worn Peacock
Butterfly were
recorded on a muggy day. A Rook
flew over.
This
small mushroom was discovered on Mill Hill just above the ridge above the
steep lower slopes.
I think this was Stropharia coronilla.

The
first Green-veined White Butterfly
of the year was seen over the path by the flowering Blackthorn
leading into scrub at the northern end of the lower
slopes of Mill Hill. Two pristine Speckled
Wood Butterflies
were seen above my head
on the Hawthorn in the copse at the top
of Mill Hill. Frequent
Peacock Butterflies
numbered at least a dozen over the lower slopes of Mill Hill.
A
passage journey over the lower slopes of Mill Hill revealed four Grizzled
Skippers visiting Dog
Violets and at least one of the first Pyrausta
nigrata pyralid
moths
of 2008.

A
Skylark
flew in station above Mill Hill, singing in the warn afternoon after the
midday hail shower.
There were three other butterfly enthusiasts on the lower slopes of Mill Hill in the afternoon, chasing around about ten Grizzled Skippers. Other butterflies recorded on the day on Mill Hill included three Peacocks and one Small Tortoiseshell.

and two Comma Butterflies.
Blackthorn
(=Sloethorn) was in flower, notably south
of the Reservoir.

Mill
Hill SMG Meeting
Despite
the awful forecast and plummeting temperature the first SMG evening field
meeting of the year at Mill Hill near Shoreham
was well attended. However, we only saw three moths - but nobody was complaining;
two were of our target species: Barred
Tooth-striped Moth, Trichopteryx
polycommata, and the other
was the micro Pale Flat-body, Agonopterix
pallorella.

Four
Peacock
Butterflies were seen in under an hour
on the downs north of Shoreham, the first
faded specimen at the top of the Pixie Path
to Mill Hill, the second and third left the lower
slopes of Mill Hill, and the fourth one was in the extreme north-west
corner of Mill Hill Nature Reserve next to
the Old Erringham pasture.

Frequent
Sweet
Violets were now to be seen flowering
on the lower slopes and under the thorn
in the scrub in the north-west corner of
Mill Hill. The cattle now
appear to have been removed, but the hoof prints and dung
were still widespread, and some were fresh.

The
cattle
were
on the flat plateau south of the upper car park. Some of the paths south
of the Reservoir were beginning to be worn from grass to mud by the hoof
prints of the cattle.
There was one cow pat
on the lower slopes and another on the
steep slope below the ridge (part of the lower slopes). There was another
cow
pat on the steps leading down to the lower
slopes which were so muddy that walking boots were advisable.
There
were a few mole hills
seen south of the Reservoir. The mounds of earth were grey.

A
male Brimstone Butterfly
settled on ivy on wall outside house in Mill Hill Drive, Shoreham at midday.
This

A

were in flower at the top of the wooded slopes on the southern section
of Mill Hill.
Around
midday
a Peacock Butterfly rose
from the lower slopes of Mill Hill and
fluttered further up the slope so I had to chase it to identify the good
condition Peacock Butterfly
when it basked briefly in the weak sunshine with its wings open.
This
was the second of two of the first February
records on these Nature Notes pages for the Peacock
Butterfly, making four species seen in the
second month of the year.

In perspective, the turf is also broken up by human trampling (as evidenced by the paths) and the burrowing of Rabbits and Moles. The cattle damage is so much more serious because it is unnecessary and the ground is fertilised as well. This fertilisation has a destructive effect on chalkhill flora, allowing common plants to flourish in the richer disturbed conditions. Sheep also cause damage in wet weather but the because of their lighter build if they are stocked at a density of up to one sheep per acre, damage to the chalkhill is acceptable.
The cattle were still trashing the upper plateau area around the car park.
28
January 2008
The
cattle
were now seen from the Adur Levels on
the richer floristic middle zone of Mill Hill, where they will do more
damage.
In
business farming terms, butterfly food plants are weeds to be eradicated.
22
January 2008
The
cattle
were still on Mill Hill dumping their excrement all over the long grass
south of the Reservoir, but also on the recovering herb-rich plateau north
of the Reservoir. Cattle
cause great damage by disturbance of the soil and nutrification with their
urine and faeces. Both these factors change the flora for a long time and
encourage grasses and ruderal plants. A dog
was seen in panic in the presence of the cattle.
Tip:
wear old shoes: the cattle
urinate
on the grass and it can be difficult to get the smell out even if you avoid
the cow pats.
Butterfly
Habitat Notes
4 January
2008
Alas
the cattle
are still trashing the top of Mill Hill in an asinine plan by the Sussex
Downs Conservation Board on an important Nature
Reserve. The flat area being grazed (seen from the Adur Levels) is
an area that contains a recovering low fertility wildlife
meadow flora including Horseshoe Vetch, Hippocrepis
comosa, and many other important caterpillar food plants and nectar
plants. The cattle indiscriminately eat the
flora, but more importantly the destruction occurs because of the ground
disturbance they cause and their patterns of urination and cow pats which
are making the paths impassable on shallow chalk soil in wet muddy conditions.
Chalkhill
herbs require low fertility undisturbed land
and are wiped out (most of them permanently) if the conditions change.

The
cattle
were not seen on a very muddy Mill Hill. However, there were still cow
pats in annoying places near the road
and on the paths near the Reservoir.
My first wild mammal of 2008 was a Rabbit on the lower slopes of Mill Hill. My first mushroom was a Blewits, Lepista sp., recorded from the ridge of Mill Hill. I originally identified this as a Field Blewits, Lepista saeva, but this species has no blue on its cap. There was no flowers to be seen on the lower slopes except for the silver leaved Carline Thistle heads. It is never quite clear with this plant as the flower heads last longer and the petals do not fall off.
I'd
go for the rather variable Lepista
sordida for this mushroom, but
you really need to measure the spores to be sure. Lepista
sordida is the only Lepista
which
can be completely blue/purple all over, but it can also have hardly any
blue at all. It favours disturbed and garden situations (probably slightly
raised fertility but overlaps in this with Wood Blewits)
Lepista
saeva doesn't have any blue/purple in the cap.

December 2007
The
South
Downs Conservation Board reintroduce cattle
gazing with a few beef cattle on the upper slopes of Mill Hill. This
is detrimental to the chalkhill flora,
possibly serious damaging and confers no advantages. The cattle were seen
from the Adur valley.
